Short summary
This paper analyses the change of total suspended sediment (TSS) and total organic nitrogen (TON) loads of the Red River from 1960–2015 in which numerous dams in both China and Vietnam have been constructed. Strong decrease of TSS and TON loads allocated to the dam impoundments in spite of population and deforestation increase. The TSS flux decrease has driven a clear reduction of associated elements (nitrogen), which let to hypothesis a change in biogeochemical processes in the coastal zone.
